USGS 3DEP The National Map

+ What is the 3D Elevation Program?

Accelerate the acquisition of high quality light detection and ranging (lidar) data in the conterminous U.S. (CONUS), Hawaii, and the U.S. Territories; and interferometric synthetic aperture radar (ifsar) data in Alaska

Completely refresh the National Elevation Dataset (NED) with new lidar and ifsar elevation data products and services

Leverage collaboration among federal, states, local and tribal partners to systematically complete national 3D elevation data coverage in eight years

Raise governance to the executive level and build on the structure already in place at the operational level under the National Digital Elevation Program (NDEP)

Increase the overall investment in 3D elevation to $146 million annually to return more than $690 million annually in new benefits

Geospatial Data Lifecycle

Office of Management and Budget Circular A-16

For more than 15 years, the USGS has managed the National Elevation Dataset (NED) and coordinated acquisition through the National Digital Elevation Program (NDEP) on a project-by-project basis

We are at a point in the data lifecycle of defining the next generation national elevation program

+ U.S. Interagency Elevation Inventory 4

2013 Status Map of Publically Available Lidar and Ifsar

Lidar: 38% of the lower 49 states has coverage Only 4 percent

meets the 3DEP goal of QL2 or better

Ifsar: 43.5% of Alaska has coverage More than half the

State needs ifsar data to complete the 3DEP goal for coverage

+ CA 3DEP activities, thus far…. Initial NEEA Survey and interviews Yearly inventory updates Workshop to reach consensus for

highest quality need for each 1-degree cell to meet all agency needs

Opportunistic partnerships for Q1 and Q2 lidar

+ Data Quality Level Choices

Bathymetric LiDAR requirements assessed for three Quality Levels to include Low, Standard and High. Standard Quality Level (3-5 meter post spacing; RMSEz ~ 20 cm)

Note – USGS LiDAR base acquisition specification version 13 is for QL3 data

Presenter

Presentation Notes

Note as Key table Quality levels are used throughout the discussion The quality level nomenclature was developed for the study so that source data could be analyzed by consistent categories. QL1 data are derived from LiDAR which is acquired at high densities of 8 points per meter. This represents the highest quality. QL5 data are derived from IfSAR and represent the lower range of quality requirements for the assessment. QL3 is equivalent to the USGS Version 13 base specification for elevation data acquisition.

READ-AHEAD BACKGROUND SLIDE This set of three functional activities is one example of an agency requirement for quality level 1 LiDAR data to address the needs of geologic hazards. The expected benefit is $31.25 million per year for operational efficiencies and hazard loss reduction to citizens as a result of improved building/development codes and better planning to avoid hazard prone areas. Other examples of business uses and associate activities include: Agriculture and Precision Farming: optimizing yields and reducing harmful runoff by site-specific application of fertilizer and pesticides, optimizing farm practices. Land Navigation and Safety: railroad grade safety and asset management, in-car navigation products and services, future intelligent navigation innovations to increase fuel efficiency. Geologic Resource Assessment and Hazard Mitigation: detailed geologic mapping to understand and mitigate landslide, seismic and volcano risks to infrastructure and populations. Natural Resource Conservation: conservation engineering, soils mapping, wetlands mapping and characterization, assessment of biological carbon stocks. Infrastructure and Construction Management: military base and facility feasibility and planning, design and placement of infrastructure, transmission line vegetation management. Flood Risk Management: flood risk analysis and flood plain mapping, emergency management, levee safety, flood forecasts, hydrologic and hydraulic modeling.

+ Steps in progress at the Federal Level

Formalize program recommendation(s) and 3DEP strategic plan

Sync USGS deliverables to better meet needs (for example, build out 1-m elevation model for the country)

One-stop shop: National Map Intensify outreach Develop outreach materials Engage key professions, industries, states, etc. Coordination with partner agencies (NOAA, FEMA, states)

Develop 3DEP funding strategy and implementation timeline

Summer 2014: first funding announcement
